Reduce Unused JavaScript Bundles
High Impact+25 points estimated
Why It Matters
JavaScript execution consumes 6.7s and blocks the main thread, preventing user interactions and delaying LCP by 14.6s.
How to Fix
Remove or defer unused third-party scripts like Postscript SDK (2.3MB unused), Wistia API (122KB unused), and TikTok pixel. In Shopify, go to Settings > Checkout and remove unnecessary tracking pixels. Use Shopify Script Tag API to load scripts conditionally based on page type.

This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This Shopify site has severe performance issues with an abysmal score of 10/100, indicating critical problems that will frustrate users and hurt search rankings. The biggest issue is extremely slow loading of the main content - your Largest Contentful Paint takes a devastating 14.6 seconds, which should be under 2.5 seconds for good performance. The primary culprits are massive amounts of unused JavaScript (over 2MB wasted), excessive CSS that's not being used (159KB), and poorly optimized images that are much larger than needed for their display size. Immediately focus on removing or deferring unnecessary JavaScript, particularly from third-party services, and properly size your images to match their actual display dimensions - these changes alone could improve your score by 50+ points and dramatically speed up your site.
Other Optimization Recommendations
Optimize Images for Mobile Display
High Impact+18 points estimatedWhy It Matters:
Oversized images waste 3.2MB of bandwidth and delay LCP by 2.1s, especially the vehicle gallery images served at 4000px for 299px display slots.
How to Fix:
In Shopify Admin, use the built-in image transformation API to serve appropriately sized images. Replace image URLs with responsive versions using Liquid filters like img_url: '300x'. For the vehicle gallery, implement Shopify's responsive image snippet with srcset for different screen sizes.
Fix Cumulative Layout Shifts
Medium Impact+12 points estimatedWhy It Matters:
Layout shifts score 0.499 (poor) due to unsized images and web font loading causing content to jump during page load.
How to Fix:
Add explicit width and height attributes to the vehicle mod highlight image and gallery images in your Shopify theme templates. Preload critical web fonts by adding <link rel='preload'> tags in theme.liquid for Poppins and Exo fonts. Use font-display: swap in CSS to prevent invisible text periods.
